About me
About me
I am a PhD student in Electrical and Computer Engineering at the University of Texas at Austin. I enrolled in Fall 2017 in the Decision, Information and Communication Engineering (DICE) track. I will be joining Qualcomm R&D in San Diego, CA as a Senior Engineer in August 2022.
I am currently working as a member of the Wireless Networking and Communication Group (WNCG) with Prof. de Veciana on network modeling and analysis projects, applied to vehicular communication and Edge/Cloud Computing.
My main research interests lie at the intersection between Mobile Networking, Edge Computing and Wireless Communications.

Ergonomic UAV Control Using Eye-Tracking (Final Year Design Project, Fall 2016-Spring 2017):
Ergonomic UAV Control Using Eye-Tracking (Final Year Design Project, Fall 2016-Spring 2017):
Implemented a hands-free HCI system to control intuitively a set of drones using eye-tracking for surveillance applications. The camera feed is received from the camera on the drone to a control room where the user can command the drone movements simply by looking at the target location on the screen. Minimizing the latency between all the sub-systems for a smooth and intuitive experience.
